In science, "fact" can only mean "confirmed to such a degree that it would be perverse to withhold provisional assent." I suppose that apples might start to rise tomorrow, but the possibility does not merit equal time in physics classrooms.

Nothing is more dangerous than a dogmatic worldview - nothing more constraining, more blinding to innovation, more destructive of openness to novelty.

We are glorious accidents of an unpredictable process with no drive to complexity, not the expected results of evolutionary principles that yearn to produce a creature capable of understanding the mode of its own necessary construction.

Science is an integral part of culture. It's not this foreign thing, done by an arcane priesthood. It's one of the glories of the human intellectual tradition.

Creationist critics often charge that evolution cannot be tested, and therefore cannot be viewed as a properly scientific subject at all. This claim is rhetorical nonsense.

Look in the mirror, and don't be tempted to equate transient domination with either intrinsic superiority or prospects for extended survival.

We pass through this world but once.

The proof of evolution lies in those adaptations that arise from improbable foundations.

When people learn no tools of judgment and merely follow their hopes, the seeds of political manipulation are sown.

The most erroneous stories are those we think we know best - and therefore never scrutinize or question.

The most important scientific revolutions all include, as their only common feature, the dethronement of human arrogance from one pedestal after another of previous convictions about our centrality in the cosmos.

Few tragedies can be more extensive than the stunting of life, few injustices deeper than the denial of an opportunity to strive or even to hope, by a limit imposed from without, but falsely identified as lying within.

The more important the subject and the closer it cuts to the bone of our hopes and needs, the more we are likely to err in establishing a framework for analysis.

At a minimum, in explaining evolutionary pathways through time, the constraints imposed by history rise to equal prominence with the immediate advantages of adaptation.

Contrary to current cynicism about past golden ages, the abstraction known as 'the intelligent layperson' does exist - in the form of millions of folks with a passionate commitment to continuous learning.

Death is the ultimate enemy - and I find nothing reproachable in those who rage mightily against the dying of the light.

Evolution is a process of constant branching and expansion.

I dreamed of becoming a scientist, in general, and a paleontologist, in particular, ever since the Tyrannosaurus skeleton awed and scared me.

I love the wry motto of the Paleontological Society, meant both literally and figuratively, for hammers are the main tool of our trade: Frango ut patefaciam - I break in order to reveal.

I'm not a great deductive thinker, but I will admit to having competence in a very wide range of things - not being afraid to try to write about baseball, choral music and dinosaurs in the same week and see connections among them.

In science, 'fact' can only mean 'confirmed to such a degree that it would be perverse to withhold provisional assent.' I suppose that apples might start to rise tomorrow, but the possibility does not merit equal time in physics classrooms.

Life began three and a half billion years ago, necessarily about as simple as it could be, because life arose spontaneously from the organic compounds in the primeval oceans.

My own field of paleontology has strongly challenged the Darwinian premise that life's major transformations can be explained by adding up, through the immensity of geological time, the successive tiny changes produced generation after generation by natural selection.

People perceive me as a commodity. They just don't think anything of asking for five minutes of my time. It never occurs to them that if they're asking for it and another thousand people are asking, I don't have 1,000 five minutes to give.

What an odd time to be a fundamentalist about adaptation and natural selection - when each major subdiscipline of evolutionary biology has been discovering other mechanisms as adjuncts to selection's centrality.

What you see is that the most outstanding feature of life's history is a constant domination by bacteria.

With copious evidence ranging from Plato's haughtiness to Beethoven's tirades, we may conclude that the most brilliant people of history tend to be a prickly lot.

The human mind delights in finding pattern so much so that we often mistake coincidence or forced analogy for profound meaning. No other habit of thought lies so deeply within the soul of a small creature trying to make sense of a complex world not constructed for it.

Always be suspicious of conclusions that reinforce uncritical hope and follow comforting traditions of Western thought.

Humans are not the end result of predictable evolutionary progress but rather a fortuitous cosmic afterthought a tiny little twig on the enormously arborescent bush of life which if replanted from seed would almost surely not grow this twig again.

As a word ecology has been so debased by recent political usage that many people employ it to identify anything good that happens far from cities and without human interference.

Memory is a fascinating trickster. Words and images have enormous power and can easily displace actual experience over the years.

Nothing matches the holiness and fascination of accurate and intricate detail.

Human life is the result of a glorious evolutionary accident.

Perhaps randomness is not merely an adequate description for complex causes that we cannot specify. Perhaps the world really works this way, and many events are uncaused in any conventional sense of the word.

Science is all those things which are confirmed to such a degree that it would be unreasonable to withhold one's provisional consent.

The telephone is the greatest single enemy of scholarship; for what our intellectual forebears used to inscribe in ink now goes once over a wire into permanent oblivion.

Great theories are expansive; failures mire us in dogmatism and tunnel vision.

The God of the Christians is a father who makes much of his apples, and very little of his children.

Second, when comparing private school and public school test scores, it's like apples and oranges. Public schools have to take everyone, but private schools can be selective. It's not accurate or fair to compare the job they do.

In science, "fact" can only mean "confirmed to such a degree that it would be perverse to withhold provisional assent." I suppose that apples might start to rise tomorrow, but the possibility does not merit equal time in physics classrooms.

Australians were unique due to our corals, our apples, our gum trees and our kangaroos.

I think one of the geniuses of Bound and The Matrix and Memento is the complete collaboration of the effort. There were no rotten apples.

I can't compare quarterbacks as apples and oranges in my mind because everybody's in a different system.

We are born believing. A man bears beliefs as a tree bears apples.

Love doesn't grow on trees like apples in Eden - it's something you have to make. And you must use your imagination too.

To compare the albums is like trying to compare apples and oranges.

Why not upset the apple cart? If you don't, the apples will rot anyway.
